A High Degree of Mental Extensity
April 7, 2006 | People & Society | Science
Here is an excerpt from a list of psychology tests from 1890.
Mental Time
- The time stimuli must work on the ear and eye in order to call forth sensations.
- The reaction-time for sound, light, pressure and electrical stimulation.
- The perception-time for colours, objects, letters and words.
- The time of naming colours, objects, letters and words.
- The time it takes to remember and to come to a decision.
- The time of mental association.
- The effects of attention, practice and fatigue on mental time.
Mental Intensity
- Results of different methods used for determining the least noticeable difference in sensation.
- Mental intensity as a function of mental time. [p.380]
Mental Extensity
- Number of impressions which can be simultaneously perceived.
- Number of successive impressions which can be correctly repeated, and number of times a larger number of successive impressions must be heard or seen in order that they may be correctly repeated.
- The rate at which a simple sensation fades from memory.
- Accuracy with which intervals of time can be remembered.
- The correlation of mental time, intensity and extensity.
I'm not sure why I'm posting this, except I like the idea of mental extensity, and while cleaning out my email in-box I'm also cleaning out my blogging drafts.
